Abstract: 108,452. Etrich, I. July 29, 1916, [Convention date]. Breaking and scutching apparatus.-The stricks of flax are fed along a table n, Fig. 1, and placed by a workman across a rotating ring R<1>, the free ends resting on a travelling band e travelling in the same direction as the ring. The ends of the stricks are pressed into grooves r, Fig. 2, in the ring by elastic cords s running over guide-pulleys l, pressure being supplied by a chain of blocks k, which are guided by wheels c, carried by levers h controlled by springs a, and by a return channel c<1>. The stricks, as they are carried round by the ring R<1>, are held in an horizontal position by a plate e<1> and are guided by a roller f to a scutching-apparatus m. The scutched ends of the stricks are conveyed to a second ring R<2> by rollers f and band e<3> where they are gripped as in the first ring. The unscutched ends are then released from the first ring and passed over a guide e<4> and rollers f to a second scutching apparatus m<1>.

[Also in Group XIII] A washing- and/or -drying machine is combined with an ironing- board 20 which in a storage position fits into a recess 14 in a flanged outer lid 13 of the machine and in a working position is supported by a pillar 21 extending from the underside of the board into a tubular socket 22 in the underside of the lid 13. The depth of the recess 14 is equal to the thickness of the board 20 so that in the storage position the lid and board form a flush surface. A latch bell-crank 24 biased by a spring 25 co-operates with vertically spaced notches 23 on the pillar 21 so that when the board is raised to its working position 9 rotated through 90 degrees the latch engages one of the notches and the board is retained in position. A groove 28 extending the full length of the pillar at a position 90 degrees from the notches is also provided so that on rotating the board through 90 degrees from the working position the latch is disengaged from the notch and biased into the groove 28 to enable the board to be lowered to another notch or into the storage position. The ironing-board may either be the same length as the machine casing or it may be extendible to a longer length and a collapsible support is then provided. The outer lid may also contain a recess 35 to store an electric iron. Specification 846,111 is referred to.

Title: Improvements in or relating to motor tractors and the combination therewith of a plough or ploughs
IPC: A01B3/56
Filed: 1919-01-25
Abstract: 140,838. Newington, F. L. G. Jan. 25, 1919. Ploughs.-A motor-tractor is provided with two sets of ploughs at one end of the machine so that one set is pulled when working in one direction, and the other set is pushed in the opposite direction of working. The tractor has a driving-wheel B, an idle wheel C, and a steering- wheel D. The motor H, which may be of an internal-combustion or a steam engine, drives the wheel B through a clutch H<2>, reversing-gearing J, and chain gearing E. The reversing- gear is controlled by a sliding fork J<4>, the first action of which is to move the direct drive pinion J' out of gear with a gear-wheel G, and a pinion J<2> into mesh with a broad pinion K, after which it slides all the pinions along until the pinion K meshes with the wheel G and gives a reverse drive. The friction clutch and reversing-gear are respectively operated by levers L<2>, L<1>. The two sets of ploughs M, T are mounted on frames P, R respectively pivoted at P<1>, R<1> to standards Q<1>, W<1> adjustable vertically in the main tractor frame. These standards are moved vertically by means of a handlever V on a shaft V<1> acting through rods Q<5>, W<5> and bell-crank levers. The trailing ends of the ploughs are raised and lowered by a hand-lever X on a shaft X<3> acting through pulleys X<2> and chains X<x>, Y<x>, so that as one set is lowered, the other is raised. The lever X is held in either of its extreme positions by a spring catch, and for travelling along roads, the set of ploughs that would be in action is held in its raised position by a bolt Z<1>. Swivel or loose joints are provided in the plough frame connexions to permit the ploughs to follow the steering of the machine.

Title: Improvements relating to the mounting of wringers on sinks
IPC: D06F45/00
Filed: 1934-05-31
Abstract: 425,436. Wringers. ACME WRINGERS, Ltd., and BURT, J. W., David Street, Bridgeton, Glasgow. May 31, 1934, No. 16217. [Class 138 (ii)] A wringer 4 is supported in the operative position, Fig. 1, over an end wall 3 of a sink 1 and when not required for use may be swung in a horizontal plane about a vertical pivot 8 and then in a vertical plane about a horizontal pivot 7 to a horizontal position, Fig. 3, adjacent the end wall of the sink and entirely below the level of the top of the sink and in this position it may be covered by lowering a pivoted table board thereover. The pivot 7, Fig. 1, is carried by a lug 6 standing up from an elongated bracket arm 5 which is secured to an upward extension 2<1> of the sink support 2 in the corner adjacent the pivot. The pivot 8 engages in an offset boss 9 in a bracket 10 which is provided with another boss 11 to receive the pin 12 projecting downwardly from the bottom of the wringer framework. The bracket 10 is provided with a buffer 15, Fig. 2, to engage the top of the sink wall when the wringer is in the operative position and with a leg 13 having a buffer 14 to engage the outside of the sink wall. When swinging the wringer about the pivot 8 the leg 11 travels along a flange 22 on the bracket arm 5. The other end of the wringer is supported when the wringer is in the operative position by means of a bifurcated clamping bracket 17 having an apertured boss 16 to receive the pin 12<1> and buffers 18, 19, 20 engaging respectively the top, outside and inside of the sink wall. To free the clamping bracket 17 from the sink wall preparatory to swinging the wringer in the horizontal plane, the wringer is tilted back somewhat about the pivot 7. When the wringer is folded down the bracket boss 16 rests on the end of the bracket arm 5 as shown in Fig. 3. Specifications 405,748 and 419,107 are referred to.

Abstract: 591,440. Thermal switches. R E V O ELECTRIC CO., Ltd., and FELTON, A. E. June 27, 1945, No. 16385. [Class 38(v)] A switch for initiating the discharge in a gas discharge lamp comprises a bimetallic strip b<6> carrying a contact b<8> which normally engages a contact b<7> carried by a metal strip b<5>, the lower ends b<4>, b<3> of the strips projecting from the annular wall of an insulating base a. The position of the contact b<7> can be adjusted by means of a screw a<1>. Surrounding but insulated from the bimetallic strip b<6> is a heating coil d the ends of which are connected to a second pair of metal strips projecting from the base a. These strips and the strips b4, b<3> form the terminals for connection to the lamp circuit, the contacts b<7>, b<8> normally bridging the gas column in the lamp. To light the lamp, current is sent through the four terminals of the switch whereby the coil d and the thermionic electrodes of the lamp are heated till the strip b<6> bends sumciently to open the contacts b<7>, b<8> thus producing sufficient potential difference between the lamp electrodes to initiate the discharge. The screw a<1> is adjusted to ensure the necessary time lag between the flow of current and separation of the contacts b<7>, b<8>.

Title: Electrical switching system and memory system
IPC: G11C11/06
Filed: 1962-04-30
Abstract: 996,496. Transistor switching circuits; circuits employing bi-stable magnetic elements. INDIANA GENERAL CORPORATION. April 30, 1962 [May 10, 1961 (2)], No. 16469/62. Headings H3B and H3T. A constant current is diverted from a first circuit successively to each of a number of transistors supplying a load. The loads may be a common transformer-fed matrix store and the arrangement provides time for each transistor and transformer to recover before they are again used, so that the store may be operated at a higher rate. When an AND circuit 25-1 produces an output pulse, transistor T 0  becomes non-conducting and the current from a constant current source 71, 26 is directed to one or other of transistors T 1 , T 2  and output transformers 31, 32 to the inhibit winding of a magnetic core matrix P 1 . Which of transistors T 1 , T 2  conducts depends upon the condition of a bi-stable circuit 40 which is changed coincidentally with the occurrence of each of the switching pulses from the AND gate. Diodes D 0 , D 1  and D 2  clamp the corresponding base potentials and diodes 33 and 34 prevent interaction between the transformer secondary windings which latter may alternatively be two windings of a single transformer. A similar circuit is provided for each core matrix, the bi-stable circuit 40 being common to the circuits (Fig. 1, not shown).
